ESTONE OZF14A HDMI Splitter 1×3

The ESTONE OZF14A is a one-input, three-output HDMI splitter designed for users who need to mirror a single 4K source across three displays simultaneously. It suits home-theatre enthusiasts, presenters, and installers who want identical content on multiple screens without extending the desktop. The unit includes a 5 V DC power adapter for stable operation.

Sustained-load behaviour and signal integrity

The splitter maintains a TMDS clock up to 340 MHz and a data rate of 3.4 Gbps across all three outputs during continuous use. It supports deep-colour modes at 8, 10, and 12 bit without signal degradation over long sessions. HDCP 1.4 compliance ensures protected content from consoles, streaming sticks, and Blu-ray players passes through without handshake drops.

Installation notes and common pitfalls

Connect the included power adapter before linking sources and displays; the unit will not function on bus power alone. Remember this device only mirrors — it cannot extend the desktop or switch between multiple inputs. The output resolution defaults to the lowest common denominator among connected screens, so a 1080p display will limit 4K sources to 1080p on all outputs.

Questions about this item

Does the ESTONE OZF14A splitter generate noticeable heat or fan noise when powered continuously?

The unit has no fan and draws little power from its 5 V DC adapter, so it runs silently and stays cool during all‑day operation.

Which cables and power source must I already have to connect three displays to this splitter?

You need one HDMI cable from the source to the input, three HDMI cables to the displays, and a mains socket for the included 5 V DC power supply.

Will the OZF14A downscale a 4K@60 Hz signal from a modern GPU so my older 1080p monitors still show an image?

Yes — the splitter negotiates the lowest common resolution across all outputs, so a 4K@60 Hz source is reduced to 1080p or 4K@30 Hz for compatibility with legacy screens.
